JUREAL BOX.

Application tiled November 5,1923. Serial No, 672,864.

To all 'uf/710m. 'it may concern lle it known that l, Bruns Fil. Kamin, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful linprovo inents in Journal loies; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others slrilled in the art to which it appertains to nialre and use the saine.

My invention relates to journal boxes and involves the production of a very streng but comparatively light .veight construction designed priinarily for use in connection with car truck side fraines of the wrought metal type in which the inner and outer walls and adjacent stiffening flanges are shaped to forni journal box recesses at the ends of the side fraine.

One of the principal features of the invention is to provide a journal boi: having ineans adapted to provide a v ry rigid and durable connection with a car truck side fiain'e, said means involving the arrangement of a plurality of advantageously located projecting portions adapted to be .tivinily united to adjacent portions of the side franie so as to produce a construction in which the relative rotating and lateral strains imparted to the box as the result of: service conditions, will be effectively rcsisted,

.flnother object of the invention is to pro- 'vide a journal box of inaiiin'iurn strength value, the top of said box being crowned to tit within a correspondingly curved journal box recess of the sido traine, said top being preferably of ribbed construction and having at least one of said ribs continued taiwnmrdly 'along one side of the journal onto forni an attaching in-einher to which the side fraine is tii'inly connected whereby the journal box is prevented from relative rotation with respect to the side frame by loads occurring in either direction longitudinally thereof.

A further object of the invention is to provide zi journal box for use with a` car truclr side fra ie having inner and outer walls ar ly extending attaching portions adapted to .embrace.neighboring portions of said, inner and outer walls, respectively, said attaching portions being rigidly connected and interlocled with the walls against relative inove nient longitudinally of the sidefraine, said interlocking connection providing a very rigid construction of both journal bei; attaching portions and the adjacent side fraine portions, whereby the loads occurring laterally of the car truck are resisted without deformation or breakage of the connected parts. v

lllith these and other objects in view, the invention further consists in the combination, arrangement and construction of the several parts hereinafter described and pointed out in the claiins.

Figure 6 is a similar view on the line 6 6 of Figure 1.

Referring to the drawings, iny improved journal box 1 is shown attached to the carl truck side fraine 2 preferably formed of wrought inetal and having an inner Wall 3 and an outer wall il. I have illustrated iny invention as applied to a oar truck side fraine formed of a sheet-metal bla-nk or blanks, but it will be understood that the present construction of journal box is applicable to other types of side frames. In the construction of side frame shown the walls thereof are formed with corresponding side fraine portions preferably reinforced with marginal inturned stiffening flanges, said flanges being preferably united by riveting or welding. The stiffening flanges 5 of the bottoni arch bar portions of the side traine are bent inwardly and downwardly, shown, the inwardly bent portions of said flanges being continued, at end of the side frame and shaped to form the curved journal box recesses 6.'

The journal box 1 includes the outer and inner end portions 7 andv 8, the former being adapted to receive the usual lid (not shown) and the latter having provided therein the dust-guard well 9. The bottomV of the journal box is indicated by the numeral 10 and the top or roof by the numeral 11, said top beingpreferably crowned to form a curved bearing surface contact-ing a similarly curved surface `of the journal box recess. Theupper face of the top 11 is provided with a longitudinally extending rib 12, said rib being intersec'ted by a plurality of transversely disposed ribs 1:3, said last named ribs intersectingthe principal bearing surfaces 14 of the journal blox disposed upon each side of the longitudinally extending rib. The crowningv of the upper face of the box provides a relatively stiff journal box roof, the shape of which lends itselfto a more satisfactory bending of the stiftening flanges forming the journal box recesses in the manufacture ofthe side frame. The relative increased depth of the top of the journal box intermediate the side edge portions provides a crowned structure which permits of the journal box being firmly seated in the recess of the side frame. rllhe upper surface of the principal bearing portions of the journal box roof and the top edges of the intersect-ing ribs are curved longitudinally of the-sideframe, said curving acting to provide an effective seating surface with minimum strains upon the adjacent metal of the side frame, and also permit of the use of a' comparatively small blank or blanks from which the side frame is formed. n

The attachingportions por lugs 15 of the journal box project upwardly from the top lthereof and are connectedv to the inner and outer walls of the sideframe, respectively, by means of rivets 16 passing through suitable openings in the lugs. Intermediate portions 17 of the attaching lugs extend inwardly of the side frame, said portions providing interlocking means with correspond ing inwardly extending portions 18 provided on the inner and outer walls of the side frame. This interlocking connection is disposed longitudinally of` the journal box axis and transversely to the direction of the loads received by the journal 'box longitu dinally of the side frame. The inwardly extending co-acting portions. 17 and 18 of the journal box and side frame, respectively, are in the nature of corrugations, the corrugations of the side frame walls adding to the relative rigidity of the side frame at the end portions overlying the journal boxes and the corrugating of the journal box attaching lugs serv-ing to materially stiften the box and also permitting the coring. out of the full areabrass lug on the interior of the box. The attaching lugs border the man1 bearing surfaces 14 from which they project outwardly at right angles thereto, reinforcportions of the respective inner andk outer walls, as best shown in Figure 1.

The longitudinally extending rib 12 at the top .of the journal box is continued downwardly along one side thereof to form another attaching lug 20 disposed centrally of the side frame, said lug, in addition to provid' ng a very rigid connection at one side of the box, also serving as an abutment member for resisting the relative rotative forces transmitted to the journal box. The attaching lug 2O is connected to adjacent depending portions 21 extending from the inturned stiifening flanges 5 bordering the lower edges of the walls of the side frame. A plurality of rivets 22 rgi'dly connect thc lug 20 to the neighboring portion of the side frame, said rivets passinf through suitable openings in the lug and being vertically arranged so as to tiethe journal box to the side frame in the most advantageous manner.

The attaching lug 20 is preferably inserted between the depending portions 21 of the side frame stiffening anges, the outer edges of which may be designed to contact adjacent portions of the journal box wall. Laterally extending bracing ribs 23 imite the attaching lug 2O with the side walls of the box from which the lug projects. Bosses 24 preferably surround the rivet openings in the lug, the relative increased thickness vof the metal incident yto the forming of said bosses being continued in the nature of ribs 25 to the journal box side wall.

In my present construction of journal box the brass and wedge are fitted about the caiaxlewithin the journal box, all in the usual manner, the standard A. R. A, dimensons being. maintained. A journal box constructed in accordance with my present invention ,is capable of being economically manufactured and easily connected to a car truclrside frame, the means employed to connect the side frame and journal box acting to resistV the strains tending to rotate the box with respect to the side frame. It will also be observed that. the interlocking association of portions of the journal box with adjacent portions of the side il .e formsA a very intimate and rigid constriction of side frame and journal box capable of resisting both longitudnal and lateral loads occurring as the result of service conditions.
